Summary
Semimembranosus tenosynovitis, a knee issue in older women, involves inflammation of the semimembranosus tendon. Surgical intervention showed good results when localized, but is not recommended for young athletes.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Musculoskeletal Disorders
Background:
- Semimembranosus tenosynovitis commonly affects women over 50.
- Inflammation occurs due to friction in the semimembranosus groove, often exacerbated by osteophytes.
- Conservative treatments include medication, ultrasound, and massage, with injections as a secondary option.
Purpose of the Study:
- To evaluate the efficacy of surgical treatment for recalcitrant semimembranosus tenosynovitis.
- To determine the outcomes of surgical intervention based on the localization of the inflammatory process.
Main Methods:
- Surgical excision of the fibrous sheath within the semimembranosus osteofibrotic tunnel was performed on 16 patients.
- A posterior medial oblique incision was utilized for surgical access.
- Patient outcomes were assessed based on the extent of inflammation (localized vs. widespread).
Main Results:
- Eight patients with localized inflammation achieved good surgical outcomes.
- Eight patients with knee joint or pes anserinus involvement experienced fair to poor results.
- Surgical treatment success was correlated with the localized nature of the tenosynovitis.
Conclusions:
- Surgical treatment can be effective for localized semimembranosus tenosynovitis unresponsive to conservative care.
- Widespread inflammation involving adjacent structures negatively impacts surgical outcomes.
- The procedure is contraindicated in young athletes due to the functional importance of the semimembranosus muscle's reflected head.
